WINDOW CONSTRUCTION.

Application filed October 22, 1909. Serial No. 524,073.

. cleaning, or for other purposes, and in carrying out my invention Iprovide the window frame with a hinged or swinging section in which thewindows may be dropped and swung out of the casing to project into theroom and permit the removal of the window sashes from the frame.

I am aware that prior to my invention attempts have been made toconstruct a win,

dow of the general type stated, but the great difficulty found inpractice has been to produce a construction wherein the movable windowframe sections will be suitably braced when swung out to preventdropping the sashes and loosening the swinging parts. In theconstructions which have come to my attention another serious objectionis present in that no suitable provision is made for protecting theswinging window section by an outside weather strip to prevent rain or.

moisture from entering between the swinging sections and the frame ofthe casing proper. Furthermore, provision has not been made to preventrotting of the sill engaging part of the swinging frame sections. It istherefore another object of my invention to produce a window of thegeneral type stated, so constructed that the swinging sections .will beas rigidly held as possible in their positions when swung out, andprotected from the weather when in position.

My invention also has for its object to provide a means for holding theswinging sections into alinement with the fixed frame sections when theparts are in their normal position, and for quickly releasing theswinging section when it is desired to remove the sashes.

My invention also includes an improved means for quickly andautomatically releasing the sash cords from the sashes andsimultaneously securing the ends of said sash cords to the win ow framein a position dented as at 3 tocoopera-te with a loo Where they may bequickly and effectively reconnected with the sash when desired.

-In its more detailed nature, my invention includes those novel detailsof construction,

combination and arrangement of parts, all of which will be first fullydescribed, then be specifically pointed out in the appended claim, andillustrated in the accompanying drawings, in which Figure 1, isaperspective view of a window embodying my invention. Fig. 2, is acentral vertical cross section thereof. Fig. 3, is an enlarged detailperspective view of .one of the connecting brackets between a swingingsection of the frame and the window 'frame casing. Fig. 4, is a detailside elevation of the latch devices for holding the movable or swingingsections in their normal positions. Fig. 5, is a section on the line 5-5of Fig. 4. Figs. 6 and 7, are detail sectional views showing themanner'of connecting and disconnecting the sash cord from the sash.Figs- 8, 9 and 10, are detail perspective viewsof the fixed framecarried plate, the connecting link with the sash cord and the fixedWindow carried plate which cooperate as indicated in Figs. 6 and 7.

Referring now to the accompanying drawin s, in which like letters andnumerals of re erence indicate like parts in all of the figures it willbe noticed that the window casing 1 may be of any approved construction,and is provided with fixed side frame sections 2 having parallel grooves2 2 for- ,the'inner and outer sashes l516 respectively. The fixed sidesections 2 have their lower ends 2 cutiofi on an approximately 45 beveland where such ends abut the easing 1, they are cut away as at 2, to beslightly spaced from said casing 1, and are further cut away at 2toreceive the latch 3. The latch 3 it will be noticed, has a head 3* toengage the endplate 5 of the swinging frame sections 4 and the latch 3is pivoted at 3 and its movement is limited by stops 3-3, as clearlyshown in Fig. 4. A leaf spring 3 in a cut-away portion 1 in the casing1, engages the latch 3 to hold it in its latching position, see Fig. 4.The latch 3 may have its spring engaging surface inor projected portion3? of the spring 3 to old the latch 3 in its latching position.

Specification of Letters Patent. 1 Patented July 18, 1911.

The swinging frame sections 4 (there being one at each side of thewindow) are 2, they having the window grooves l l to register with those22 of the sections 2, and the sections 4 have their upper ends beveledat t" to contact the ends 2 of the sections 2, when in their normalposition. In order to hold the sections 4 and 2 in proper alinemcnt tomake a continuous uninterrupted groove 2 --4, or 2 4 as the case may be,from the top to the bottom of the window, when the parts are in theirnormal position, I provide a plate 5 secured in the countersunk portion4 of the frame sections 4, which plate enters the cut-away portions 2 ofthe sides 2 when the sash is in its normal position and the latch 3 hasits head 3 to engage the plate 5 and lock the sections 2 and t togetherwhen the sections 2 and 4 are in alinement. The lower edges of thesections 4 are square cut to leave a space between said lower edges andthe sill 17 as shown by dotted lines 18 in Fig. 2, to prevent water andmoisture rotting said lower edges.

The casing l, where it joins the sill is countersunk to receive thehinge plate 6 and it is further countersunk at 1 to permit movement ofthe clip 7 of the hinge plate 7 hereinafter again referred to. The hingeplate 6 is of circular arc form having a vertical edge (3 and a frontportion 6 held in a plane at right angles to the plate 6, the portion 6*having curled hinge ears 6, through which and through similar ears 7 ofthe front plate 7* of thehinge section 7,

the hinge. pin 8 passes. The hinge section 6 has its plate 6 secured inthe countersunk portion of the casing l by screws that pass throughapertures 6 in the plate. The plate 6 at its upper end has a stop 6 andnear its lower end has a second stop 6 to limit the movement of thehinge section 7 by having its clip 7 engage said stops at the limit ofmovement of the hinge section in either direction. The hinge section 7comprises the side plate 7 which is secured to the sides of the windowsash by screws 7 that pass through the plate 7 as shown in Fig. 3, theplate 7* abutting the plate 6 of the other hinge section 6 and having apart cutaway and bent toform a clip T to securely hold the sections 67in contact. The hinge section 7 also includes a front plate 7 that issecured in a countersunk portion of the window sash at the front andheld in place by screws 7 as shown in Fig. 3, of the drawings. Thus itwill be seen a very rigid hinge connection is provided for the sashesbetween the windows and frame to prevent lateral movement of theswinging frame sections toward one another to drop the sashes whenpositioned as shown in Fig. 1 and by projecting the plates 'Z"6 incontact with one another and holding them in eeaoia contact by the clip7* the strain is largely practically duplicates of the fixed sections 1removed from the hinge connection 678.

Any suitable sash balancing means may be provided to balance or sustainthe weight of the sashes, although I have shown in the drawings a springdrum sash balance means 13 mounted in the chamber 14 at the top of thewindow casing 1 from which the sash cords or ribbons 13 pass down oversuitable pulleys (not-shown) into the grooves Q Q". I have not shown thepulleys and the details of construction of the sash balancing means 13,as such per se form no part of my present invention.

The sash cords or ribbons 13 at their free ends are secured to doubleeye members 11, one end 11 of which joins with the sash cord or ribbonl3 and the other end 11 is adapted to connect with the sash. The doubleeye member has a central brace portion 11 and is bent along the line ofits brace member so that the two eye portions-1ll1 will lie in differentplanes.

Hook plates 9 are secured to the sides of the window sash by screws orother suitable means, and the plates 9 have hooks 9 opening outward tothe window frame. Se cured in the grooves 2 -2 at any suitable location,preferably at the position indicated in the drawings, are tongue plates10 which are countersunk into the frame and lie flush, the tongue plates10 having downwardly directed tongues 1O which project into alinementwith a hole 2*, which may be bored or "otherwise provided in the framesections 2 to receive the eye 11 of the double eye member 11 to retainthe sash cord in a definite position while the cords are being removed.

The manner of connecting the sash ribbon or cord with the sash and withthe tongue plate or fixed cord sustaining member forms one of theessential features of my invention, as by its use rapid connection anddisconnection between the sash cord and sash may be made and at the sametime the sash cord or ribbon can be automatically shifted fromconnection with the sash into connection with the fixed holder, or viceversa, as conditions may require. The con struction of this part of myinvention is best disclosed in Figs. 6 to 10 inclusive, by reference towhich it will be noticed that when the parts are in their normalposition,

as shown in Fig. 6, the tension on thesash cord 13 is directed in thedirection of the arrow w in Fig. 6, and by reason of the eyeportions11"l1 lying in different planes and bent at the bridge 11,the'bridge serves as a fulcrum, causing the double eye member 11 to actas a lever, as it were, to move the eye member 11 in the direction ofthe arrow y in Fig. 6 when connected with the hook 9 In order todisconnect the sash cord from the sash, the sash is moved until the hook9 is oppositethe hole 2* and tongue 10, as shown in Figs. 6 and 7 Theoperator then grasps the sash cord or ribbon 13* adjacent to the eyemember 11, or he grasps the upper end of the eye member 11 and pullsdownward on the sash cord or ribbon in the direction of the arrow 2 inFig. 7, and inwardly in the direction of the arrow :1: in Fig. 7, whichcauses the eye member-11 to move in the direction of the arrow y in'Fig.7 and automatically and simultaneously disconnect the eyemember 11 fromthe hook 9. and move it into the hole 2 into engagement with the tongue10 to hold in that position until it is again ready to connect the sashcord with the sash when the movements just described are reversed. Thusit will be seen that with one action the sash cord is disconnected fromthe sash and connected with the fixed holder on the frame to be inposition for reconnection with the sash whenever desired. Furthermore byconstructing the member 11, as shown and described, the tension on thesash cord 13* when the parts are positioned, as shown in Fig. 6, one ateach side of the sash (it being understood, of course, that theinvention is applied to each side of the sash) will serve to hold thesash centered in the frame and reduce considerably the friction of thesides of the sashes in the grooves, as shown in Fig.6, thus making iteasy to raise and lower the sashes and prevent chattering of the windowsash in the grooves, during the action of.

raising and lowering,

'Any suitable locking means may be provided for locking the sashes intheir various positions and as such means form no part of my presentinvention illustration and detailed description thereof is thought to beunnecessary in this specification.

In operation the latch 3 is elevated when it is desired to swing thesections 4 to the posit-ion shown in Fig. 2, and the sash cords orribbons 12 are isconnected from the sashes after the sasheshave beenpocketed or moved into the sections 4, after which said sections areswung to the position shown in .Fig. 4, when the window sashes may bebodily removed forcleaning or other purposes.

A weather strip 1 is provided on the outside of the casing 1 to preventmoisture ensaid are tering between the contacting faces of the sections2 and 4 and the casing 1, and as before stated, by providing the spacesbetween the lower ends of the sections 4 and the sill 17, as indicatedby the dotted lines 18, when the parts 4 and2 are in alinement, rottingof said lower ends and the sill is prevented.

In the application I make no claim to the specific form of latch devicesfor holding the movable section of the window frame in'position, nor doI make any claim to the specific form .of sash cord connectingmechanism' shown and described, as such form the subject-matters of twodivisional applications.

From the foregoing description taken in connection with the accompanyingdrawings it is thought the complete construction, operation andadvantages of my invention will be readily understood by those skilledin the-art to which the invention appertains.

WhatI claim is:

In a window construction a. frame includsaid side strips having theirends adjacent to the sill cut to lie inv a horizontal plane and therebyproviding a. space between said lower ends and said sill,- sashreceiving members, means for hingedly mounting said sash receivingmembers in said frame to be hinged adjacent tosaid sill,sa.id sidestrips having arc grooves the center of curvature ofwhich isvat saidhinging means,plates countersunk into said side strips and projectingover said are grooves, fingers carried .by said sash receiving membersto project into said arc grooves and engage the face of said plateswhere they project over the respective arc grooves, and stops carried bysaid plates to engage said fingers and limit the movement of said sashre ceiving members on their hinging means, rooves extending to thebottom edge of said side strips to communicate with the space betweenthesill and the bottom edges of said side strips,and having their otherends terminating within the side strips.
